I just bought a 2002 z28 it already had 241 heads and a xr265hr-15 comp cam so with that being said pump more air in shouldn't bigger injectors and a upgraded fuel pump be next I'm new to ls power plants and tuning a computer controlled car so just asking

 

Both stock pump and injectors can support your power level. Its never a bad idea to upgrade the fuel system but its not must right now. I would recommend upgrading if you intend to carry on modding and pushing more power.
